I can't seem to find the capacity of the front and rear differentials on my 88 K5 Blazer. Their both 10 bolt 8.5 ring gear. Please help !

I don't know if any of you ever used "Liqui Moly" products ( Their German oil products) I first put the ATF additive in my old Pontiac Gran Prix, the transmission wasn't bad but it shifted hard and I had already installed a larger trans fluid cooler. So I suctioned about 10 oz. out of the transmission pan and put in the Liqui Moly ATF additive and the transmission never shifted hard ever again. Bitter cold or stiffing hot. I have done the same thing to my 88 Blazer and again it took the rough edges off the transmission operation. I just had the rear transfer case seal replaced and (I hate this, I gave the shop a quart of Mobil Synthetic ATF) so I got my Magic Creeper and slid under the Blazer and took off the upper threaded plug, and nothing came out. I asked them to top off the transfer case, but I had to put a pint and a half for it to start flowing out the hole, I left it off with a oil drain pan under the transfer case till it stopped flowing out. But there are times I have to wonder if I'm speaking English ? What is so hard about "Please top off the oil" when your done. I know you folks think it is a minor issue, but Why can't a shop get something so minor done ?

There is nothing hard about it. Have you used the shop before? If this was a one time oversight it's one thing but if it's happened in the past I might look into another shop. Was it on the work order? They either failed to list it on the work order or failed to follow the work order.

At any rate I would let them know they failed to top it off like you asked.

Yeah it's a local shop and have had a good relationship with the owner. I told him directly and handed him the quart of Mobil Synthetic ATF. And he's done a lot of work on both the 90 Silverado and the 88 Blazer. I even bought a Pizza a liter of Pepsi for lunch yesterday. But I'm getting to a point were I need to get a shop who can do what I want and at their best scale of workmanship. The shop I go to charges $75.00 an hour, so if I can find something like that so be it. but If it takes a little more money to get my repair done right then I'll accept what ever good craftsmanship costs. If I wan't 65 and a tired 65 I'd do it myself, and many things I can do on my own. It's just some jobs I need to farm out.

Sometimes you can find a topnotch guy who moonlights piecemeal work. You don't come across them very often. The best way to find them is word of mouth from family and friends. I had a guy like that years ago when I was living in Houston. I was in an apartment and didn't have access to a garage.

If you ever do find a guy like that pay him well and help keep him in business.
